(54) Title: VAPOUR SUPPRESSION ADDITIVE (57) Abstract: A process for removing CO 2 from a CO 2 containing gas stream in which the CO2 containing gas stream is contact ed with an aqueous ammonium solution. The aqueous ammonia solution comprises 0.1 - 40 % w/v, v/v/ w/w ammonia, and a solu N ble salt at a concentration range of 0.01 % - 10% wt or v/v or w/v, the soluble salt having cations selected from the group of group IA, IIA, IIIA and IVA metals with counter anions selected from the group of anion of group VIIA elements, NO 3 -, SO42, OH-, P0 4 - and HCO 3-. The invention also extends to a CO 2 capture solvent comprising an aqueous ammonia solution and the above snhihle salt
